Flame retarded Thermoplastic Polyurethane (TPU) for cable jacketing application

Fire resistant TPU formulations containing different amounts of a melamine based flame retardant (i.e. melamine cyanurate) and nanoclays have been studied. The synergism between melamine cyanurate and clay in composites thermal stability and flame resistance have been assessed by means of thermogravimetry and combustion tests, namely LOI and cone calorimeter. Composites mechanical and theological properties have been also evaluated. (c) 2012 Elsevier Ltd. All rights reserved.
